MILTON D. WHIPPLE, OF BRIGHTON, ASSIGNOR OF ONE-HALF HIS RIGHT TO LUTHERCRANE, OF CAMBRIDGE, MASSACHUSETTS.

IMPROVEMENT IN WADDING, BATTING, ttc., AND IN MACHINES FOR MAKING THESAME.

Specification forming part of Letters Patent No. 123,136, dated January30, 1872.

To all whom t may concern:

Be it known that I, MIL'roN D. WHIPPLE, of Brighton, in the county ofMiddlesex and State of Massachusetts, have invented a new and usef'ulImprovement in the Manufacture of Wadding, Batting, and Carpet-Lining;and I do hereby declare that the following is a full and exactdescription of the same, reference being had to the accompanying drawingmaking a part of this specification.

My improvement relates mainly to the tem or mode of condensing orcompressing a web or sheet of batting which has passed through thecommon card and been formed into a lap, or after the cotton or otherfibrous substance has been fed to a machine on an apron and taken theform of a lap during its passage through feeding-rollers.

The main point of novelty is the inode of inter-lacing or combining thefibers of the lap, this being effected in such a manner as to produce astrong and condensed web or sheet without the use of paper, paste, orsewing.'

The fabric is suitable for various purposes, and consists entirely ofthe same materials that the batting operated upon is composed of, a partof the fibers being thrust through the fabric from one or both sidesthereof, thus binding or interlacing the materials.

Figure I is a side eleva-tion of the machine. Fig. II is an end view,showing the needles and vibrating frames. Fig. III is a plan of theLipper part of the machine.

The main drivin g-wheel is represented at A, and carries a pulley on theeccentric shaft C. A shaft, D, extends across the machine, and a pulleyafxed to it drives the pulley F and the shaft G. This shaft and itsaffixed pulleys drive the scrollpulley I and the front rollerpulley J.The cotton or bat is fed to the niachine upon the endless apron B, andpasses between the horizontal rollers E E', by which it is carriedforward between two series of vertical pins or needles, Q Q'. Theseneedles are slightly roughened or barbed. They are tapered, and are ofsufficient length to pass through the bat. They are set in the top barsM M' of the two vertical frames S S', which are moved up and down by thepitmen L L', which are carried by the eccentrics K K' at tached to thebottom shaft C. The pitinen are jointed at R R', so that the frames S Smay traverse vertically. The needles may be set diagonally, as shown atQ, Fig. III, the upper series of rows being so placed as to enter thespaces in the lower series. To assist in clearing the needles, and toprevent the bat from rising or falling too far when the needles arewithdrawn, there are two perforated plates, O and O', placed parallelwith the needle-holders M M'. These plates are fixed as to theirvertical position, but are movable back and forth horizontally by theattached arm l?, the end of which is bent at right angles, and is movedby the scroll-cam N. As the needles pass rapidly through the bat orsheet a part of the fibers is carried upward and a part downward, andthe result of this interlacing is the production of a condensed and hrmfabric, which now passes forward to the delivery-rollers H H', fromwhich it issues ready for packing and use.

The iinished article resembles a felted fabric, as it is held togetherby the crossing and intcrtwining of the fibrous substance of which it iscomposed.

In some cases a single series of needles, M, may be used, all of thefibers that form the iuterlacing being thrust through the bat from thesame side.

To produce a fabric that is condensed at one part and light at anotherpart, the needles or pins may be placed in detached groups. When theseare moved to the right or left by the scroll-cam N across the web,curved or diagonal lines are produced.

What I claim, and desire to secure by Letters Patent, is-

l. The series of needles or pins, slightly roughened or barbed, set in asuitable frame or holder, and made to traverse back and forth through abat or web of cot-ton or other fibrous substance, for the purpose ofinterlacing and condensing the fibers, substantially as hereindescribed.

2. I also claim, as a new article of manufacture, a bat, web, or sheetmade as hereinbefore described.
